Be it known,d that I, GUsrAv Eason, a, citizen of the United States, residing 1n the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in P ffir This invention relates to improvements in eum'oil, and as for its obiect the crac ofthe maximum of light hydrocarbon oil by causing Ithe oil to pass through controlled reaction paths or chambers.v The invention will be understood from the following description, r'eference be had-to the accompanying drawing, in which the represents a somewhat diagramma o side elevation `and vertical section of .my improved apparatus` Referring the drawings (1), designates th f -in which is mounted heating w 'ch, if desired, may take the fm of 2,000feet or 4more ofiour inch cycle tubing.
